Question 316364: Which of the following points is on the graph of the equation y = x2 ?

A. (-2, 4)
B. (-5, 10)
C. (5, 10)
D. (4, 8)

Solve the equation by finding the square root of both sides: 3x2 = 27
A. x = 3 and x = 27
B. x = 1 and x = 9
C. x = ±3
D. x = ±√3

Solve the equation by completing the square: x2 + 2x - 8 = 0
A. x = 2 and x = -8
B. x = -4 and x = 2
C. x = 8
D. x = 1, x = 2 and x = -8

Solve for y: y2 + 12y + 11 = 0.

A. y = 1 or -11
B. y = -1 or -11
C. y = -1 or 11
D. None of the above

Solve the equation by finding the square root of both sides: 5x2 = 125
A. x = ±√5
B. x = ±5
C. x = 5 and 125
D. x = 1 and 25
